Q:How does the two phase step motor connect

The two phases are four lines, and the two of them are A set of lines, called A and B, and the four lines come out to the drive A, A, B, and B

Q:A step into an electric motor can have two step angles, such as 3 degrees / 1.5 degrees. What does that mean?

Motor inherent interval Angle: it said control system each hair a step pulse signal, motor rotation Angle. Motor factory is given a step away from the Angle of value, such as 86 byg250a type motor is given a value of 0.9 ° / 1.8 ° (half step work step 0.9 °, the whole work was 1.8 °), the interval Angle may call it the 'inherent interval Angle motor, it is not necessarily the actual step motor work pitch Angle, the actual interval Angle and drive on. (2) the number of phase stepper motor

Q:What are the advantages of step-motor versus private motor?

The servo motor has more than one feedback function, namely, one coder. The stepping motor and servo motor are both the receiver of the upper machine pulse or the analog model to control the rotation Angle and speed of the motor. But the step motor has no feedback function to run the ring. The servo motor has the encoder feedback, for the closed-loop operation. So the accuracy of the servo is higher than the step motor, and the accuracy of the servo motor depends on the encoder resolution.

Q:What is the way in which the step motor ring is distributed?

The first step should be to understand the mechanism and principle of the step motor, which is the rotor of a permanent magnet, and how many different slots are on the rotor. A stator is a phase winding 2) the rotation principle, which circulates the various phase wheels into direct current, creates a rotating magnetic field, which is rotated by the rotating field. The faster the magnetic field spins, the faster the motor spins

Q:The step motor knows how to subdivide, how do you figure out the number of pulses required to turn a circle

When choosing 6400, the number of pulses required to run a motor is 6,400 pulses.

Q:What are the advantages and disadvantages of stepping into the motor?

The advantages of stepping motor are as follows: The maximum torque when the motor is suspended (when the winding excitation); The rotation of the motor is proportional to the number of pulses. 3. The response of the motor is only determined by digital input pulses, and thus can be used in a open loop control, which makes the structure of the machine is relatively simple and control cost; 4. Due to the precision of each step from three percent to five percent, and would not step error accumulation to the next step and has good location accuracy and repetitive movement; Excellent stop and reverse response; Because there is no brush, the reliability is high, so the life of the motor depends only on the life of the bearing. Simply connecting the load directly to the rotor of the motor can also rotate at a very low speed.

Q:What is the step motor

Step motors, by definition, are the motors that move in step, and a controller sends out pulse control signals. For example, when the step motor turns into a 360 degree, the controller is set to 1000 steps for 360 degrees, and the controller sends a thousand pulse signals to the controller. This type of motor is commonly used for locating accurate equipment

Q:The step motor and the servo motor are big

They say so much is crap, look at the parameters, torque. In addition, the step motor usually has no big power motor, servo has. Heavy load or servo.

Q:How does the step motor reset

By adjusting the air ratio of the pulse width modulation signal, the amplitude is constructed by a sine drive current that is attenuated by a certain pattern. At a certain phase difference with the current in the stepping motor's winding, can give in motor drive in micro step way, and the torque attenuation by the desired pattern. This method is applied to the stepper motor to zero process, can make the motor at a constant speed and torque gradually weakened the way back to zero, effectively protect the motor and drive gear. This method does not require hardware circuit, but can make the motor return to zero reliability, the motor runs smoothly. So there is a wide range of applications

Q:What is the torque of the step motor

Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller. The torque is related to the torque of the stepping motor. The greater the torque, the greater the torque. There are three main types of stepper motors: the equation of Variable, VR, Permanent Magnet, PM, and Hybrid Stepping, HHS. Step motor and driver selection: To determine how much torque is required: static torque is one of the main parameters of the step motor. Large torque motor is required when loading. When the torque indicator is large, the motor is also large. To determine the speed of the motor: when the speed requirement is high, the electric motor with a large current and low inductance should be chosen to increase the power input. The higher power supply voltage is applied when selecting the drive. The installation specification of the motor is chosen: 57, 86, 110, etc., which is mainly related to the torque requirement.
